TAPE ATTACHMENT.

Specification of Letters Patent.

PatentedFeb. 22,1916.

Application filed November 10, 1914. Serial No. 871,231.

To aZZ whom it may concern:

Be it known that I, JoHN A. JoHNsoN, a citizen of the United States, and a resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Tape Attachments, of which the following is a full, true, and exact specification.

y invention relates to tape attachments and has for its principal objects; to provide a device which is attachable to the end of a tape for the purpose of holding the said end of the tape while making a measurement; to provide a device of the foregoing description which may readily be pivotally attached to the loop which forms the end of most steel tapes as found on the market.

Other objects will appear as my invention is more fully described in the following specification, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings the figure is a side elevation of my device, shown attached to the end of a steel tape.

Referring more particularly to the drawings, numeral 1 designates a fragment of a steel tape having a loop 2 at the end which is adapted to engage a clip 3 by means of a pin 4. The clip 3 has an upstanding'projection 5 which is provided with teeth 6 on its inner face. The ends of the teeth 6 stand at substantially right angles to the body of the clip 3*. Oppositely disposed from the projection 5 is a stud 9, which is provided with a threaded projection 10, said projection being adapted to screw into a threaded hole 11 in the clip 3 The plane B B, which passes through the ends of teeth, also passes through the center of hole 11. When it is desired to measure the distance from center to center of two circular holes of different size as is common in steel work, a stud 9 of the proper dimension to just fit one of the holes is selected and screwed into hole 11 in clip 3 The stud is next inserted into the hole for which it was selected, the tape pulled taut and the dimension to the center of the other hole read direct without any calculation. Upon the stud 9 is a bushing 9, over which is, in turn, sleeved a second bushing9", the bushing 9 being held to the stud by friction and the other bushing being held to bushing 9 from the spirit same manner. The purpose of the bushings is to obviate the necessitypf changing the 1 stud to suit holes of varying sizes, as will be understood. The dimension starts from plane B B in this case. By the use of my tape attachment, it is possible for one person to take measurements of considerable distances where previously another person was required to'hold the end of the tape; thus it will be understood that in many cases my device takes the place of one person in taking measurements. Much of the possible inaccuracy, due to having some one hold the end of the tape on a given point, is obviated as my device takes a positive hold where placed, and, by use of the modified form, the exact distance from center to center of the hole is quickly and positively shown. I

The above described device is particularly useful in the building trades, in the fabrication of structural steel, in machine shops, etc.

I have shown a particular form of embodiment of my invention, but I am aware that many minor changes therein will suggest themselves to others without departlng and scope of the invention and I do not, therefore, desire to be limited to the form shown and described.

l/Vhat I claim as new and desire to protect by Letters Patent, is-

In an attachment for tape lines, the combination of an angular member and means for attaching one leg of the member to the tape line, whereby the other leg is at a right angle to the tape line when the latter is taut,

the last mentioned leg being provided with teeth for more securely holding the member to an object, a 7 leg which projects in an opposite direction to that of'the toothed leg which is adapted to engage the edge of an aperture, a set of bushings which are adapted to sleeve over each other and the entire set to be mounted upon the said lug, whereby the distance may be measured from the centers of apertures of varying sizes to the center of another aperture.
